Inheritance diagram for otb::TransformationFunctorDispatcher< TransformationFunctor, TransformedElementType, FieldTransformationPolicy >:

Detailed Description

template<class TransformationFunctor, class TransformedElementType, class FieldTransformationPolicy = FieldCopyTransformation>
class otb::TransformationFunctorDispatcher< TransformationFunctor, TransformedElementType, FieldTransformationPolicy >

Policy to call the transformation functor on OGRGeometry (even when the actual transformed element is a ogr::Layer).

Template Parameters

TransformationFunctor	actual transformation functor
TransformedElementType	geometries to transform. This policy-class is specialized for ogr::Layer and OGRGeometry.

This functor dispatcher is meant to work:

• on a single ogr::Layer (in that case, it acts as a in-place filter).
• or on a pair of ogr::Layer s (in that case, it acts as a copy filter).

Specializations are expected to provide:

• a typedef TransformedElementType which is expected to match TransformationFunctor::TransformedElementType;
• one overload of operator() one that takes a reference to a ogr::Layer for in-place transformation;
• another overload of operator() one that takes a const reference, and a reference to ogr::Layer for by-copy transformation;
• and one overload to operator->() that returns a pointer to the actual TransformationFunctor.

  Since

  OTB v 3.14.0

  Todo:

  Add a specialization for ogr::Feature.
